Recently reformatted my computer (Windows 7 64 bit) to fix a few previous problems, and now have a new one.
I have the XFI Fital1ty Xtreme Gamer Edition, along with Logitech X540 speakers. I have the latest driver for Windows 7 64 bit, and have the speakers correctly connect into the sound card. I have triple checked this confirming with the online manual. My problem is that the sound positioning keeps getting all screwed up. I have it set to 5.1 in both the Creative control panel and the Windows 7 manager. I was playing Bad Company 2 for about 5 min, when all of a sudden all the sound was coming from the center and rear speakers. I go into the windows sound tester and it plays that little bing noise in the rear speakers first, then goes to the front opposite of what the animation says it should do. Then I go to music play a song, check it again and its back to normal. I have never had this happen to me before. I don't understand, I have everything connected correctly and all drivers up to date.
Now i do still have my on board card enabled, which i use specifically with an earpiece for Team Speak. But before I reformatted my PC I always used it like that without a single problem. I don't have any drivers installed for that, and it works fine for what i use it for.
If anyone can help me that would be much appreciated.
did some research and the only two thoughts I have
1) creative drivers are notoriously bad-possibly try an older version if available
sometimes latest drivers will have unknown glitches
2) try a different slot for card if possible - sometimes cards will work better in other slots-has to do with IRQ assignment though it is rare
try to only go one or two drivers older if possible
Just to let you know
if your device is working well do not update driver
many people think they have to constantly use updated drivers
but really if the device is performing the way it should and you are happy with it
leave the driver alone
especially video card and sound card drivers
